The offset was changed to allow room for ABS sensors on the 'late'r cars. Not all later cars had ABS, but all had the extra room for it.

For some reason that I cannot figure out, people think that the fitment of a wheel is entirely dependant upon offset. This of course is not true, being as how offset is a function of the wheel's width (in this situation).

Porsche made 15x7 Phonedials in three different offsets, and 15x7 Fuchs in at least two different offsets.

Take care,
